Where .deb files are stored in Ubuntu ?

We always hear people saying ubuntu works well only when you have a strong internet connection as the Install CD doesn't contain all the packages required agreed now a CD cannot contain all the packages you require so you need to download the packages but there is a clear misunderstanding among new users that they always need to download these packages, Its essential to download them once but if you are reinstalling ubuntu on new machine you need not download these packages all over again if you have installed required packages on one of the machine you can use the content of below listed directory for installation

/var/cache/apt/archives

this directory contains the debian packages download by the apt-get :)

so have fun reuse the content for each install and save time and bandwidth
